*2. subject of the King be Italy, residing at Turin, in Italy, have invenlcd certain new and useful Improvements in for Erecting Walls and the Lil e, which the followingis a specification.

This invention relates to machines for constructing Walls and the like, which greatly simplifies the masonry Work by limiting the ositioning oi the materials within s definitely fixed space.

The machine determines with precision the position of thc'hlocks or bricks consli tilting the Wall and alsospreads the morfair, which the workman has only to simply lay on said'hlocks or bricks. Means may also, be provided to compress and equalize each row of bricks or the like as they are laid on the bed of mortar. y

Figs. 6 and 7 are respectively side and end. elem: tions representing a modified construction of machine. Fi 's. 8 and 9 are detail vie-ws illustrating parts shown in Figs 6 and '4'.

In the construction shown in Figs. 1 and 2, themachine comprises a framework consisting of the uprights 1 and cross pieces 1,

and mounted. on Wheels 2. On the uprights 1 cross pieces 3 are shdshly mounted, the

height of which can be regulated by means of the crank l gearing 5, 5'aiid 2. chain:

the cross pieces by means oi": suiishle cords; or the like 8, 8.

To the cross pieces Bare oonncctedlhe two guides P) on which the apparatus may moved. or displaced.

In the form shown in Figs. 6 to 9, the machine is supported by lateral cpri; on each of which is slidehly mom." sleeve 27 fixed to a cross piece 33 A i with guides 9 on which iilie corn 2 T the machine can he moved f "splsced iiheaid of smell wheels 10. up? h has along all its length 2. guide maybe graduated and the s ecrc '2'?

on said npright'msy-be fixed at the desired height by means of a set screw 29 which forces the checks of said sleeve firmly against the lateral walls of said guide 28. On (he sleeve 2? is mounted a drum 30 operated by means of a hand Wheel 31 and on which is Wound a cord 8 Whicl1 after having passed over a roller 7 is attached to the cross piece 3 and thus permits of missing; or lowering some by aciuation of said hand Wheel 31. A member 9 carrying the guides is carried by a sleeve 33 movable along the cross piece and can be fixed in the desired position by means of a setscrew 32 which presses'the sleeve 33 on to a guide 34 which. projects from the cross piece 3. The upright 1 is 5311;?0141- ed in the manner shown ll'l detail in 1g. 9, which allows of readily fixing it in any poe is will he seen from the drawing the upright is concealed at its lower end to a member provided below with a hemispherical recess 35 engaged by a sphere 36 carried by s. hose 3? which is attached in any snit'ahlc wy-to the scaffolding. A

mounted so as to he leterslly movable. The distance between said frames 11 can be regulated according to the position and thickness of the Well, by means of ahand crank 12 actuating the screw spindle'12 en gaging nuts 13 attached to the frames 1-1. At the lower ends of the frames 11 are mounted two lateral plates .14 arranged as shown in Fig. 3'to arrest the mortar ata certain distance from the edge of the facing hloclzs or bricks,- in orderto prevent said mortar owing out when i the corresponding bricks of the next row are placed in position.

method of mounting r 5 to allow of placing the first row of ic s or the advance of the apparatus in accordance with proniinences of the wall. In the arran ment shown in Fig. 5 keys 16 are provi' ed by which the plates 14 and 15 can be rigidly theplates 14 and are rigid with the same during the operation of the machine. The connection between the plates 14 and blades 15 is preferably detachable, to allow of re moving the same in case of need, but while in use the said two members 14 and 15 are united and operate like a single plate bearing against the outer faces of the outer bricks and extending upward to prevent the mortar spread upon the wall from fallin On the plates 14 are mounted rods 17 whic allow ot'limiting with precision the face of the wall, and are adapted to be slid axially so as not to hinder the movement of the apparatus when it is adjacent an anglein the wall.

The device for spreading the mortar'comprises two trowels for example of triangular section to form as a whole an extensible device which can occupy the whole width of the wall whatever the distance between the two lateral plates 14 on which the two trowels 18, 19 are mounted. This arrangement of partially superposed members is rendered necessary because the thickness of the wall and consequently the distance between the two plates may vary. The two trowels can be overlapped more or less according to-this'width and form a continuous transverse device traversingthe Wall. the trowels is mounted on a guide 20 carried by the plates 14 by fixed to the end of the trowel. The mortar spreading device can thus be moved along the plates 14 of the apparatus without however being able to rise or fall. The inclination of the walls of the trowels .18, 19 has the effect of compressing the mortar which collects in front of them during their forward movement with the apparatus and of causing it to penetrate the interstices between the bricks or blocks of the course below. As the trowels 18 and 19 can move freely relatively to the plates 14 when the apparatus advances, this device obviously passes to its extreme rearward position where they are arrested by the cross pieces 17 in which the rods 17 have bearing, but if desired it'is possible to cause the trowels to advance alone so as to spread the mortar on the surface of the wall covered by the apparatus.

instead of arranging the plates 14 and 15 so that the former form an edge directed toward the interior of. the Wall, intended to prevent. the mortar from reaching the face 1 of the wall, plates 14 and 15 can be ar- 18, 19 arranged to overlap so as Each of.

ranged to term a singl'e snrface'fdir i'cted-to Fig. 7 and appliedjto:

ward-the wall as in the two ends of the trowels 18,19, the lat: tel-"having below abutments 39. which reach to the surface of-the bricks laid, and which durin the movement of the apparatus to sprea the mortar scrape the latter which was carried to the edge of ,the wall and which projected therefrom when laying the next course of bricks,

The operation of follows: The support is arranged on the scaffolding and the height of the justed according to requirements, the lateral plates 14 being also adjusted according to the thickness of the Wall. .The said plates 14 (which in the construction shown in Fig. 3 bear on the ed e of the wall at their inner faces) form witi the horizontal surface of the wall a mold in which the mortar is spread. Wfheninoving the frame 10 along the guides 9, the trowels 1.8 and 19 which partially overlap each other and occupy the entire width of the wall, spread the mortar in anniform layer which only leaves uncovered that portion of the facing bricks which corresponds to the edges of the wall, owing to the extension of said plates toward theinterior. By facing bricks I refer to the bricks forming the outer vertical surface or surfaces of thewall; If there is a set-back or angle in the wall it is necessary to place at this point a stop device of any kind to produce the same action as the edges of the plates 14 for preventing the mortar fromreaching the edges of the bricks and the trowels 18, 19 will be caused to advance separately in order to spread the mortar equallyin the space occupied by the apparatus. A layer of mortar is thus obtained on which the next course of bricks is laid which is accomplished by placing the facing bricks against the rods 17 and then conveniently filling the space between said facing bricks. To locate the support for the machine at the necessary place and regulate the height of the guides 9; in the construction of Figs. 1 and 2 the frame constituted by the uprights 1 and the cross pieces 1 is moved on the wheels 2 and the cross pieces 3 are raised or lowered by'means of the crank 4, and parts operated thereby. In the support shown in Figs. 6 to 9, the sleeve 38 is unscrewed so as to enable the upright 1. to be inclined in any desired direction and consequently the cross piece 3 is brought to the desired height. When the desired position is attained the said sleeve is screwed up again which secures the upright by pressure on the sphere 36. To raise the cross piece 3 and the whole apparatus with it, the drum 30 is rotated by means of the hand wheel 31. When a course has been laid a layer of mortar is spread thereon by shifting the frame 10 and so on.

guides 9 ad- 75 the machine. 15 as It will be understood thatwith the machine described the work of the bricklayer is simplified and the positioning of the materials is limited within a space definitely fixed by the machine which is operated similarly for all the courses of the wall it the guides 9 are raised when necessary. The machine is portable so thatlit may be displaced and adjusted according to the nature of the wall to be constructed.
